USING THIS SYSTEM AT EXCESSIVE VOLUMES CAN CAUSE PERMANENT HEARING DAMAGE.
USE AS LOW A VOLUME AS POSSIBLE.
W
ARNING!
In order to use this system safely, avoid prolonged listening at excessive sound pressure levels. Please use the following guidelines established by
the Occupational Safety Health Administration (OSHA) on maximum time exposure to sound pressure levels before hearing damage occurs.
90 dB SPL at 8 hours
95 dB SPL at 4 hours
100 dB SPL at 2 hours
105 dB SPL at 1 hour
It is difficult to measure the exact Sound Pressure Levels (SPL) present at the eardrum in live applications. In addition to the volume setting on the
Personal Monitors, the SPL in the ear is affected by ambient sound from floor wedges or other devices. The isolation provided by the fit of quality
earpieces is also an important factor in determining the SPL.
Here are some general tips to follow in the use of this product to protect your ears from damage.
• Turn up the volume control only far enough to hear properly.
• Ringing in the ears may indicate that the gain levels are too high. Try lowering the gain levels.
• Have your ears checked by an audiologist on a regular basis. If you experience wax buildup in your ears, stop using the system until an
audiologist has examined your ears.
• Wipe the ear molds with an antiseptic before and after use to avoid infections. Stop using the earphones if they are causing great discomfort
or infection.
110 dB SPL at ½ hour
115 dB SPL at 15 minutes
120 dB SPL — avoid or damage may occur
READ these instructions.
KEEP these instructions.
2.
HEED all warnings.
3.
FOLLOW all instructions.
4.
DO NOT use this apparatus near water.
5.
CLEAN ONLY with dry cloth.
6.
DO NOT block any ventilation openings. Install in accordance with the manu-
7.
facturer's instructions.
DO NOT install near any heat sources such as radiators, heat registers, stoves,
8.
or other apparatus (including amplifiers) that produce heat.
DO NOT defeat the safety purpose of the polarized or grounding-type plug. A
9.
polarized plug has two blades with one wider than the other. A grounding type
plug has two blades and a third grounding prong. The wider blade or the third
prong are provided for your safety. If the provided plug does not fit into your
outlet, consult an electrician for replacement of the obsolete outlet.
PROTECT the power cord from being walked on or pinched, particularly at plugs,
10.
convenience receptacles, and the point where they exit from the apparatus.
ONLY USE attachments/accessories specified by the manufacturer.1.
11.
UNPLUG this apparatus during lightning storms or when unused for long periods of
12.
time.
REFER all servicing to qualified service personnel. Servicing is required when the
13.
apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus
has been exposed to rain or moisture, does not operate normally, or has been
dropped.
DO NOT expose the apparatus to dripping and splashing. DO NOT put objects filled
14.
with liquids, such as vases, on the apparatus.
15.
Remove the batteries from the receiver if the system will not be used for a long
period of time. This will avoid any damage resulting from a defective, leaking
battery.
16.
DO NOT throw used batteries into a fire. Be sure to dispose of or recycle used
batteries in accordance with local waste disposal laws.
